Death
Assessment: This product has a wide margin of safety in cats following labeled use. If some product residue was ingested, mild GI upset may occur. The onset of signs 1 week post-application is unusual and severe signs progressing to death do not fit the toxicological profile of the product. Other causes including unknown trauma, toxin exposure, congenital conditions, infectious diseases, and severe flea anemia should be considered following sudden death in a young cat. Without diagnostics, this case cannot be evaluated further. The information contained in this report is based on self-reported statements provided to the registrant during telephone interview(s). These self-reported descriptions of an incident have not been independently verified to be factually correct or complete descriptions of the incident. For that reason, information contained in this report does not and cannot form the basis for a determination of whether the reported clinical effects are causally related to exposure to the product identified in the telephone interviews.
